USCIS FOIA Request for I-140 information (Sample G-639)

Dear Anilji,

I have a query regarding the FOIA request we raised for my spouse’s I-140 approval copy please. Detailed scenario as below:
Request #1 - Sent email with scanned copies of notarized documents (Form G-639 + Passport) - no response received over 30 days

Request #2 - Tried to raise a request online, attached scanned copies of notarized documents (Form G-639 + Passport) - upload kept failing. So rebooted my computer and raised request #3 as below

Request #3 - Raised request online successfully with notarized documents attached (Form G-639 + Passport) and also got a ‘Control Number - NRCXXXXXX’

Now I have received a mail by post from USCIS asking to prove self identity with a UNPXXX-. I think this may be due to Request #2 where the documents failed to get uploaded.

Question: What should I do now?

  1. Send them the notarized copies and give them the NRC control number that I was able to successfully generate on the 3rd attempt?
  2. Ignore that mail and let them process Request #3?
    Please advise. I dont want them to reject either of the requests due to any duplication.

Thank you so much,
Namz
